Sampling Times/Pulse Frequency - Siemens SINAMICS S120 Commissioning Manual

5.7.3.7

Sampling times/pulse frequency

Overview
From a pulse frequency of 800 Hz and higher, we recommend that you enter the sampling times
and the pulse frequency for the drive.
Note
You can only activate or deactivate the "Sampling times/pulse frequency" function when you are
offline.
Setting the defaults
The sampling times are preset via parameter p0112. To make the presettings, proceed as follows:
1. Select one of the following defaults via the drop-down list (p0112):
– [0] Expert
– [1] xLow
– [2] Low
– [3] Standard
– [4] High
– [5] xHigh
The designation of the defaults refer to the desired output frequency and control dynamic
response. If a particularly high output frequency or control dynamic response is required,
"xHigh" would be the correct default. The selected default affects the following control loops:
– p0115[0]: Sampling times for internal control loops, current controller
– p0115[1]: Sampling times for internal control loops, speed controller
– p0115[2]: Sampling times for internal control loops, flux controller
– p0115[3]: Sampling times for internal control loops, setpoint channel
– p0115[4]: Sampling times for internal control loops, position controller
– p0115[5]: Sampling times for internal control loops, positioning
– p0115[6]: Sampling times for internal control loops, technology controller
The display of the parameter values set for p0115 changes depending on the default setting
made.
Note
If the sampling times of the current controller and speed controller are changed (see also
p0115), it is recommended that the controller settings are recalculated via p0340 = 4 after
the commissioning (p0010 = 0).
